You basically summed up my BF4 experience. Once I stopped complaining and started trying to adjust my play I went from a .6 kd there to a 1. Would most likely be higher if I kept going. Now though I don't really care, and my try hard days are over for the most part. I never took Destiny's PvP that serious though, and saw it as mostly unbalanced crap. Not because of OP junk, but rather the poor map design, lag, and cheaters.
